Metal hose pavement construction requirements

Metal hose construction, the use of sub-construction method, previously used in the original arch culvert base angle side by side two, the length determined based on long culvert. Culvert advance for the rails, corrugated culvert pipe diameter according to project needs may have different specifications, ready to pipe diameter of 0.5m - 2.5m; each section of pipe length 3 meters. Using internal (external) flange bolts. Assembled pipe diameter of 3m - 8m. Each circumferential direction 4 --- 15 plates, lap board and the board strength bolts tightened. If Han longer than 30 meters, the corrugated culvert culvert sides of the original width of less than 80cm, length 3m-6m may be downstream or upstream culvert advance toward the one end, in place later, it can be fixed to the top of the sheet rock masonry end wall, the other end of the corrugated culvert culvert with sandbags or the distance between the mortar and stone block, width 50cm, then start filling. Both sides of the law can be dense or coarse watertight concrete pouring Vibes tamping; top with high-pressure pumping expansive cement mortar. This section tube four weeks after they have finished filling the second pipe shipped to carry two connections, corrugated culvert pipe are connected to the inner flange bolting, workers in the pipe connection. After connecting to the same method as backfill. In this order, to complete the construction of the entire road corrugated culvert work. Metal hose adapter, according to the selection of electrical equipment into the cable connector metal hoses and metal Hydraulic hose fittings , metal hose fittings according to the size of the transition metal hose connector panel mounted connector and metal hose, so that the whole system is naturally smooth; transition joints can either press the need to produce at the construction site can also be mass-produced in the factory according to standard parts, with the use of promotional value; cable can extend the life of the cable to be effective in preventing injury leakage and other external forces generated security incidents.
